Very true... and it's about the fourth or fifth time I've said that...but no one ever checks... Good to see you're on your toes.

Doesn't really poison the fishies if it is intact and on the boat.

They have started using carbon fiber and kevlar in the high end PWCs haven't they???

My own ship has a big fat lead keel encased in glass fibre.... the ship is a Union 36, with a modified-full keel. Now into her 30th year, the keel is zero maintainence, so far.... no visible corrosion, and no keel bolts!!!!

Cast iron is likely to be a good material too. Despite the association with steel (there is a lot of iron in steel !) cast iron really does have good corrosion resistance (witness raw water cooled Volvo motors... cast iron).
It is a rather brittle material though.

I keep some tungsten and lead aboard... in the form of buckshot and slugs to help repel PWCs... Amazing what damage a good slingshot can do with a .50 caliber Tungsten pellet.
